net/rds: correct socket tunable error in rds_tcp_tune()

BugLink: https://bugs.launchpad.net/bugs/1953731
commit 19f36edf14bcdb783aef3af8217df96f76a8ce34 upstream.

Correct an error where setting /proc/sys/net/rds/tcp/rds_tcp_rcvbuf would
instead modify the socket's sk_sndbuf and would leave sk_rcvbuf untouched.

Fixes: c6a58ffed536 ("RDS: TCP: Add sysctl tunables for sndbuf/rcvbuf on rds-tcp socket")
